This works for me.
Perhaps you updated your executable, but not
the other files.

I'm trying to run -xtmixed- in Stata 9.1 SE, Windows XP,
after successfully
using it in Stata 9.0.
I keep getting the same error message no matter what my model
specs are (see
below). Finally I tried copying Example 1 from the -xtmixed-
section of the
panel data manual.
I downloaded the "pig" data set used in the example and tried
the code
listed there:
. use http://www.stata-press.com/data/r9/pig
(Longitudinal analysis of pig weights)
. xtmixed weight week || id:
last estimates not found
r(301);
The "not found" error message is the same problem when I use
my own data
set.
Am I doing something dumb or is -xtmixed- broked in Stata 9.1?
